I'm in the process of setting up my speakers for a 6.1 setup and was wondering if I should use the test tones coming from the receiver or the Video Essentials test tones in order to setup my speakers? Is there a difference. I'm asking because the only way I can setup my speakers on my reveiver(KENWOOD 6070) is by going thru the test tones. Also when setting up my sub will the BASS PEAK feature change any settings that I've made earlier? Thanks in advance for any help!
